INVENTOR ne Shane rdon l'Vf/sgp A ORNEY Q m n W A L Patented Sept. 8, 1931 UNITED STATES PATENT OFFICE JOHN STONE STONE AND GORDON WILSON, OF SAN DIEGO, CALIFORNIA ADVERTISING DEVICE Application filed December 13, 1930. Serial No. 502,016.

This invention relates in general to ad conjunction with advertising display espevertising devices.

One of the objects of this invention is to provide an advertising device belonging to that class in which the attention of the pub lie is attracted by an unexpected motion and in which its attention is held by an expectation of a repetition of the motion.

A further object of this invention is the provision of mechanism in connection with a display device such as a bust or picture of a man or woman on the bill board or other display surface associated so that clouds of smoke or a compound simulating smoke issue from the mouth of the bust or picture to indicate the act of smoking.

A further object of this invention is the provision of mechanism of this type arranged so that the smoke is caused to issue periodically in puffs at reasonable intervals from the mouth of the bust or picture.

A further object of this invention contemplates mechanism employing chemicals Which are properly mixed and caused to issue in puffs periodically to simulate tobacco smoke.

These and many other objects as will appear in the following disclosure are successfully attained by means of this invention.

This invention resides substantially in the combination, construction, arrangement and relative location of parts, all as will be set forth in details below.

Referring to the drawings:

Figure 1 is an elevational view with some parts in cross-section and some parts broken away of the apparatus comprising this invention;

Fig. 2 is an illustration of a bust of advertising device or display with the smoke discharge arranged so that the smoke will issue from the mouth of the bust;

Fig. 3 is an illustration of a picture display of a man on a display surface or advertising board with the smoke discharge associated therewith so that the smoke issues from the mouth of the pictorial representation. v

The prime object of this invention is the provisionof a simple mechanism for use in cially in connection with the advertising of smoking paraphernalia such as cigarettes, cigars, smoking tobacco, pipes and the like.

It is, of course, apparent that the principles of this invention and the construction involved may be applied to any form of advertising device in which intermittent puffs of smoke would be used to attract attention.

The invention may be said generally to relate to that class of advertising devices in which the attention of the public is attracted by an unexpected motion and in which its attention is held by an expectation of a repetition of the motion. The invention is, of course, adapted to make forms of advertising and has only been shown in connection with bust and pictorial representations for purposes of illustration. I

The term smoke is used in this specification to designate visible vapors, smoke or fog resembling tobacco smoke and in order for the smoke to have such an appearance, the mean diameter of its particles should not too greatly depart from 2.5 x 10- cm., which is the mean diameter of the particles of tobacco smoked. The vapor of ammonium chloride (NH Cl) or sal ammoniao has particles Whose mean diameter is 10 cm. and is therefore indistinguishable from tobacco smoke, but fogs or mists, the mean diameter of whose particles are of the order of 10' cm., have still suflicient resemblance to tobacco smoke to be used for the purposes of this invention. This invention proposes to make use of both of these smokes or aerosols.

When a fog or mist is used,-they are generated by producing pulfs of the vapor of someof the tetrachlori'des, such as TiCh, SnCh SiCl or other extremely hygroscopic substances such as SO These vapors, because of their pronounced hygroscopic properties, attract moisture from the air and produce a fog or mist. These vapors may be accompanied by' a certain proportion of ammonia (NH vapor which neutralizes the acld odor of the vapor. ater vapor in the form of hygroscopically saturated air, a

may also be added simultaneously to the sembles tobacco smoke.

13 and valve 11, through pipes 16 and into containers 17 and 18. The ammonium hydrate is siphoned drop by drop from container 25 through pipe 26 into container 17. It reacts with the unslaked lime producing amonia which fills all the free upper space in container 17. Likewise hydrochloric acid is siphoned from container 31 drop by drop through pipe 32 into container 18. Due to its greater affinity for water the sulphuric acid in container 18 absorbs the water from hydrochloric acid falling therein resulting in the collection of hydrochloric acid gas in the top container 18.

As the piston 7 falls downwardly, air is forced into containers l7 and 18 creating a pressure therein and forcing an amount of ammonia gas and hydrochloric acid gas through pipes 33 and 34, depending upon the volume of cylinder 5. The intermixing of the ammonia gas and hydrochloric acid gas in the atmosphere results in the formation of ammonium chloride which, issuing in puffs from pipes 33 and 34, closely re- The frequency and volume of the puff of smoke depend upon the frequency of movement of piston 7 and the volume of cylinder 5 and the diameter of the capillary bores in pipes 26 and 82. As the reagents gradually siphon from containcrs 25 and 31,'the space left by their removal is taken up by dry air which flows thereinto through pipe 21, container 22 and pi e 23 and pipe 27, container 28 and pipe 29 respectively. As already pointed out, containers 22 and 28 contain any suitable material for drying the air as it passes therethrough.

It is pointed out that the resulting ammonium chloride fumes are in no way injurious to humans, being it anything, rather beneficial even though blown into a comparatively small shop or room.

From the foregoing disclosure it will be apparent that we have embodied certain principles of construction and operation in one physical form of apparatus for purposes of illustration and it will likewise be apparent that these principles may be embodied in other physical apparatus without departing from the spirit and scope of this invention.

We do not further desire to be strictly limited by the disclosure as given in an illustrative sense but rather to the field of invention as defined in the appended claims.
